			This panel lets you add 
			<font color="red">MapLayers</font> to your map.
		</p>
		<p>
			A <strong>MapLayer</strong> is basically a textured, polygonal-shaped area. 
			To select a new <font color="red">MapLayer</font> you need to retrieve a folder containing 
			a list of <font color="green">MapLayer Concepts</font> 
			(use the <font color="blue">Browse Concepts</font> button). 
			<font color="green">Concepts</font> are then displayed in the space below: 
			to select one of them just double click on it.
		</p>
		<p>
			After that you have to retrieve a folder containing a list of 
			<font color="green">MapLayers Renderers</font> 
			(use the <font color="blue">Browse Renderers</font> button). 
			<font color="green">Renderers</font> are then displayed in the space below: 
			to select one of them double click on it.
		</p>
		<p>
			To draw selected <font color="red">MapLayers</font> on your map, you can move your mouse 
			cursor over the <font color="green">Display</font> and form a polygonal shape 
			<font color="blue">click after click</font>. 
			Clicked points will be considered as the polygon vertexes.
			<font color="blue">Double click</font> on the last vertex to automatically complete the 
			polygonal shape. While drawing the polygon it is always possible 
			to <font color="blue">right click</font> in order to erase the previous vertex.
			You can even erase the polygon entirely by pressing escape (<font color="blue">Esc</font>) 
			button.
